"Our parents were taken. And if we go home, the Nazis will take us too...."

Hamburg, 1938. Fifteen-year-old Asta is hurrying home from school with her twin brother, Jurgen. The mood in the city is tense - synagogues have been smashed with sledgehammers, and Asta is too frightened to laugh as she used to.

But when she and Jurgen are stopped in the street by a friend, her world implodes further. Her Jewish parents have been dragged into the streets by German soldiers, and if she and Jurgen return to their house, they will be taken, too.

Heartbroken at the loss of her parents, Asta knows they must flee. With her beloved brother, she must make the perilous journey across Germany and into Denmark to reach their only surviving relative, her aunt Trine, a woman they barely know.

Jammed into a truck with other refugees, Asta prays for a miracle to save herself and Jurgen. Crossing the border is a crime punishable by death, but she and Jurgen must embark on a dangerous crossing on foot, through the snowy forest dividing Germany and Denmark. And when barking dogs and armed soldiers find Jurgen and Asta escapes, she must hold on to hope no matter what. One day she will find her twin, the other half of herself. Whatever the price she has to pay....

Fans of Fiona Valpy, Kristin Hannah, and Catherine Hokin will be gripped by the story of a brave brother and sister seeking safety during one of the darkest times in our history.
